  The Quantum Threat to Cybersecurity Quantum computers will be able to solve problems that are far too complex for classical computers to figure out. This includes solving the algorithms behind encryption keys that protect our data and the Internet’s infrastructure.  Much of today’s encryption is based on mathematical formulas that would take today’s computers an impractically long time to decode. To simplify this, think of two large numbers, for example, and multiply them together. It’s easy to come up with the product, but much harder to start with the large number and factor it into its two prime numbers. A quantum computer, however, can easily factor those numbers and break the code. Peter Shor developed a quantum algorithm (aptly named Shor’s algorithm) that easily factors large numbers far more quickly than a classical computer. Since then,  scientists have been working on developing quantum computers that can factor increasingly larger numbers.   Today’s...

AI Cyber Security in AI   Faster Threat Detection and Response Leveraging AI helps you better understand your networks and identify potential threats faster. AI-powered solutions can sift through vast amounts of data to identify abnormal behavior and detect malicious activity, such as a new zero-day attack. AI can also automate many security processes, such as patch management, making staying on top of your cyber security needs easier. It can help you respond faster to attacks by automating specific tasks, such as rerouting traffic away from a vulnerable server or alerting your IT team to potential issues. Improved Accuracy and Efficiency AI-based cyber security systems provide improved accuracy and efficiency compared to traditional security solutions. For example, AI can scan scads of devices for potential vulnerabilities in a fraction of the time it would take human operators to do the same task. Furthermore, AI algorithms can recognize patterns that may be difficult for the hum...

  Blockchain offers a different approach to cybersecurity due to its inherent nature as a decentralized system. This  decentralized architecture  significantly reduces vulnerabilities commonly exploited in centralized systems. Other inherent blockchain cybersecurity benefits include: Robust encryption methods . In blockchain, each data block is encrypted and linked to the previous one, forming a tamper-resistant chain. This cryptographic structure ensures data security and integrity, making any tampering attempts evident. This makes blockchain well-suited for securing sensitive data and financial transactions, and for keeping reliable digital records. Immutable records . Nobody can modify records on blockchain. If you want to make a change in the record, you will have to make a new transaction, and both the original and the new transactions remain visible on the ledger. This unchangeable record-keeping is a key cybersecurity advantage, deterring fraud and maintaining data...

  In May of 2000, a young hacker in the Philippines named Onel de Guzman created an email worm that would change the way the world thought about cybersecurity. De Guzman had just dropped out of college after his professors rejected his undergraduate thesis paper, on the possibility of using malware to steal internet passwords from people in the neighborhoods nearby. The ILOVEYOU  virus  comes in an email with "ILOVEYOU" in the subject line and contains an attachment that, when opened, results in the message being re-sent to everyone in the recipient's Microsoft Outlook address book. Perhaps more seriously, it results in the loss of every JPEG, MP3 and certain other files on all recipients' hard disks. Since  Microsoft Outlook  is widely installed as the default email management application in corporate networks worldwide, the ILOVEYOU virus can spread rapidly within a corporation. In fact, this is exactly what happened on May 4, 2000. In just about 10 days, ILOV...

  What is Petya ransomware? Petya is a strain of  ransomware  that was first identified in 2016. Like other types of ransomware, Petya  encrypts  files and data on the victim's computer. The operators of Petya demand payment in Bitcoin before they will decrypt the files and make them usable again. Unlike some older ransomware strains, which only encrypt certain important files in order to extort the victim, Petya locks up a computer's entire hard disk. Specifically, it encrypts a computer's Master File Table (MFT), making it impossible to access any files on the hard disk. Petya has only been observed targeting computers with Windows operating systems. How does Petya ransomware spread? Similar to many other ransomware attacks, Petya spreads mostly through email attachments. Attackers send emails to HR departments with fake job applications attached. The attached PDFs either  contain an infected Dropbox link  or are  actually executable files in di...

  Zero Days (2016):A documentary focused on Stuxnet, a piece of self-replicating computer malware that the U.S. and Israel unleashed to destroy a key part of an Iranian nuclear facility, and which ultimately spread beyond its intended target. Stuxnet is a computer worm that was originally aimed at Iran’s nuclear facilities and has since mutated and spread to other industrial and energy-producing facilities. The original Stuxnet  malware attack  targeted the programmable logic controllers (PLCs) used to automate machine processes. It exploited a previously unknown Windows zero-day vulnerability to infect the targeted system and spread to other systems. The virus primarily targeted separators at uranium enrichment plants in Iran. However, cyber attackers have modified and adapted it over time to attack other facilities, such as power plants and gas pipelines. No country has officially acknowledged the development of Stuxnet, but it is widely believed that the United States ...

Equifax, one of the three largest consumer  credit reporting  agencies in the United States, announced in September 2017 that its systems had been  breached  and the sensitive personal data of 148 million Americans had been compromised. The data breached included names, home addresses, phone numbers, dates of birth,  social security numbers , and driver’s license numbers. The credit card numbers of approximately 209,000 consumers were also breached. The Equifax breach is unprecedented in scope and severity. There have been larger security breaches by other companies in the past, but the sensitivity of the personal information held by Equifax and the scale of the problem makes this breach unprecedented.  Chinese Military Charged with Equifax Breach:  The U.S. government has  indicted  four members of China's military on charges of hacking  Equifax  to exploit the personal data of 150 million Americans. They allegedly conspired to hac...

  The first attack on our list is the WannaCry ransomware attack. This attack hit businesses and organisations all over the world in May of 2017. The WannaCry ransomware encrypted data on victims’ computers and demanded a ransom payment in order to decrypt the data. This attack affected more than 200,000 computers in 150 countries. The WannaCry ransomware attack was particularly dangerous because it exploit a vulnerability in Microsoft Windows that had been previously unknown. This meant that many organisations were not prepared for this type of attack. The WannaCry ransomware also spread quickly, thanks to a feature that allowed it to spread itself from one computer to another. While the WannaCry ransomware attack was devastating, it could have been much worse. Fortunately, a  security researcher discovered a kill switch  that stopped the spread of the malware. However, this did not stop the damage that had already been done. In  total,  the  ransomware...

The Cyber attacks  are on the rise, and they show no signs of slowing down. In fact, many experts believe that we are only seeing the tip of the iceberg when it comes to cybercrime. As businesses continue to move their operations online, they become increasingly vulnerable to cyberattacks. In this blog post, we will take a look at the five most dangerous cyberattacks in history. These attacks have caused billions of dollars in damage and affected millions. The WannaCry Ransomware Attack (2017) Equifax Data Breach Stuxnet The NotPetya Virus (2017) I LOVE YOU

The attackers who stole $81 million (£55.8 million) from the Bangladesh central bank probably hacked into software from the SWIFT financ The 2016 Bangladesh Bank heist is a notable example of a sophisticated cyber attack on the SWIFT network. Here's a step-by-step breakdown of the key technical aspects of the attack In the cyber-security industry the North Korean hackers are known as the Lazarus Group , a reference to a biblical figure who came back from the dead; experts who tackled the group's computer viruses found they were equally resilient. Little is known about the group, though the FBI has painted a detailed portrait of one suspect: Park Jin-hyok , who also has gone by the names Pak Jin-hek and Park Kwang-jin . 1. Initial Compromise Phishing Attack: The attackers initially compromised the Bangladesh Bank's system by sending spear-phishing emails to employees. These emails contained malicious attachments, which, when opened, installed malware on the bank's netw...

Cyber security frameworks are sets of documents describing guidelines, standards, and best practices designed for cyber security risk management. The frameworks exist to reduce an organization's exposure to weaknesses and vulnerabilities that hackers and other cyber criminals may exploit. A cybersecurity framework is a set of policies, practices, and procedures implemented to create an effective cybersecurity posture. These frameworks provide organizations with the guidance to protect their assets from cyberthreats by identifying, assessing, and managing risks that could lead to data breaches, system outages, or other disruptions. NIST Cybersecurity Framework ISO 27001 and ISO 27002: International Organization for Standardization. SOC2: Service Organization Control (SOC) Type 2.

7 LAYERS Cybersecurity shouldn’t be a single piece of technology that improves security. Rather, it should be a layered approach with multiple facets to ensure comprehensive protection.   It’s important to understand what a layered approach consists of. Generally, there are 7 layers of cybersecurity to consider. Below, we explore what these are and why they are important.    The Human Layer Humans are the weakest link in any  cyber security  strategy, and they are alone responsible for 90% of data breaches. Mission-critical assets are protected from a variety of human threats, such as cybercriminals, malevolent insiders, and careless users, by human security controls including phishing simulations and access management rules. Security Strategy:  Education and training, which include instructions on how to recognize and deal with phishing attacks, strong password strategies, system hardening, and cyber security awareness, are the best ways to keep the h...
